One of the activities that distinguishes Zambia – our African safari destination of choice – from most other countries, is the facility for taking to your feet in the bush, on a walking safari, accompanied only by your guide and an armed scout. However, under Tanzanian National Park rules, this is not possible in most Tanzanian destinations, although there are some locations in which this can be done – ask for details.
In principle you don't get quite as close to big game as you would in a vehicle (although in practice it can turn out to be just the opposite!), but you also get the opportunity to study things - such as insects, trees, droppings and spoor - that you normally never observe from a vehicle.
Walking safaris are not particularly strenuous - you will be stopping frequently to observe the fascinating details of the bush so the pace is not brisk by any means, but you will be travelling over rough terrain. Walks tend to last for 3 to 4 hours with a mid-walk break, setting off early in the morning and arriving at your next lodge or campsite at around 10 or 11 in the morning to avoid walking during the hot midday sun.
